APPARATUS FOR FILLING STARCH-DRYING WAGONS.

Specification of Letters Patent.

Application filed January 2'7, 1913.

To all whom it may concern:

Be it known that I, Fnnnmon L. JEF- rnnins, a citizen of the UnitedStates, residing at Summit, in the county of Cook and State of Illinois,have invented certain new and useful Improvements in Apparatus forFilling Starch-Drying Wagons, of which the following is a specification.

My invention relates to the manufacture of starch, and particularly tothe system of drying starch after it is taken from the settling tableswhich has been invented by Louis I. Bauer and disclosed in United StatesLetters Patent granted to the in ventor August 13, 1912, No. 1,035,302.The characteristic feature of this system of drying is that instead ofspreading the starch out on trays which are carried in horizontalposition through the drying tunnels, the starch is dried in wagonsprovided with narrow compartments having foraminous sides and extendingfrom top to bottom and from end to end of the wagon, these compartmentsbeing spaced apart so that spaces are provided for the circulation ofhot air.

The object of my invention is to provide an improved form of apparatusfor filling the wagons in a system of this sort; the inventionconsisting in a simple but eflicient apparatus whereby the starch may betrans ported from the starch tables, broken up into particles smallenough to enter the starch compartments, and uniformly dis tributed inthe different compartments of the wagon. I lay no claim to theconstruction of the wagon.

The invention is illustrated, in a preferred embodiment, in theaccompanying drawing wherein Figure 1 is a sectional View takenlongitudinally of the conveyor and transversely of the wagon; Fig. 2, adetail section on line 2-2 of Fig. 1; Fig. 8, a plan view, and Fig. 4, aview, in perspective, of a slatted structure employed for preventing thestarch from entering the circulation spaces in the wagon.

Like characters of reference designate like parts in the several figuresof the drawing.

Referring to the drawing, A designates a belt conveyer which transportsthe starch from the settling table (not shown) to the place of loadinginto the wagons.

B designates a starch wagon which is di vided, by suitable foraminouspartitions,

into a number of starch compartments C and intervening circulationspaces D which extend from top to bottom of the wagon from end to endthereof, and are open at the top; the construction of a wagon of thissort being shown in Patent No. 1,035,302 above referred to. The conveyerA terminates at the open side of a box or housing E which is preferablyentirely open at the bot tom. The wagon to be filled is positioned underthis housing. l/Vithin the housing and preferably at its forward side(having reference to the direction in which the wagon is moved whilebeing filled) a breaking element consisting preferably of a roller F,the shaft G of which is mounted in suitable bearings and provided with apulley H for the driving belt J the roller being provided with prongs K.Pivotally mounted in the housing above the end of the conveyor is avalve or deflecting member L, a spring M preferably being employed tonormally force the valve against the end of the conveyer. The purpose ofthe member L is primarily to govern the delivery of the starch from theconveyor. The lumps of starch vary in size and the distribution upon thebelt is not always equal. The belt will ordinarily be run at quite ahigh speed and if some means were not provided for intercepting andcontrolling the delivery of the starch from the belt it would be likelyto be thrown over to the farther side of the wagon. The deflector ismanipulated by means of acord N which extends over a sheave O on a shaftP mounted in the housing. A man standing on the platform Q, by givingthe deflector an appropriate angular position, which may be varied ascircumstances require, can properly distribute the starch as it comesfrom the belt. The wagon as filled is gradually moved forward, that is,in the direction shown by the arrow in Fig. The breaking roller is keptin constant rotation and serves to break up the lumps of starch.

In order to prevent the starch from entering the circulation spaces D aslatted structure B (Fig. 4) is placed upon the wagon, the slats beingarranged to cover the circulation spaces.

Ordinarily the starch wagons are filled one after another by acontinuous operation. In such case, when a wagon has been filled, thedeflecting member L is allowed to bear against the end of the conveyerand serves as a valve to hold back the starch until the filled Wagon isremoved and an empty one put in its place. Preferably a scraper S isprovided which is secured to the housing and bears against or standsclose to the belt A.

.I claim:

In feeding apparatus for starch Wagons of the character described, thecombination with a continuously operating conveyer, of a housing open atthe bottom and having an open side into Which the conveyer delivers,

a deflector pivoted to the housing above the delivery end of theconveyer and provided With manually operated means for changing itsangular position, a spring which tends to force the lower end of thedeflector against the delivery end of the conveyer, and a rotarybreaking element in said housing below the conveyer.
